在数字信号处理中，fir滤波器是必不可少的。本代码主要是实现对于数字信号处理中的fir滤波器，对各个样点进行操作。源码需要在linux环境下运行。

基于LINUX系统编写的一款TCP/IP传输加速软件。常用于卫星通信方面，TCP/IP加速源码。linux!-Commonly used in satellite communications, TCP/IP speed up the source, based on linux!

链表是一种物理存储单元上非连续、非顺序的存储结构，数据元素的逻辑顺序是通过链表中的指针链接次序实现的。链表由一系列结点（链表中每一个元素称为结点）组成，结点可以在运行时动态生成。每个结点包括两个部分：一个是存储数据元素的数据域，另一个是存储下一个结点地址的指针域。 相比于线性表顺序结构，操作复杂。由于不必须按顺序存储，链表在插入的时候可以达到O(1)的复杂度，比另一种线性表顺序表快得多，但是查找一个节点或者访问特定编号的节点则需要O(n)的时间，而线性表和顺序表相应的时间复杂度分别是O(logn)和O(1)。本代码是实现了c语言实现链表的基本操作，如创建链表，增加节点，删除节点，查找节点。

linux下操作串口的应用程序，可以配置波特率，停止位，校验位等，实现字符模式下对串口的操作，通信等。

在linux平台下运用开源QT软件，C++编写常用图形化仪表，可以将数字信号转化为图形仪表信号，显示在windowform当中，代码使用简单，方便初学者学习与运用！

相信大家对Apache都有所听闻，Apache是目前使用最为广泛我Web服务器。但无奈自己水平有限，无法从Apache庞大的source code里面理清头绪，于是乎，我就冒出了个自己动手写一个小型的简单的Web服务器的想法，希望对这方面也和我一样感兴趣的朋友有所帮助。
